Allergies and Anaphylaxis

by Dec 10, 2017

Anaphylaxis, or anaphylactic shock, is the most serious allergic reaction that can cause death without prompt medical attention. If a susceptible individual is exposed to an allergen, or ‘trigger’, the person can have potentially life-threatening symptoms such as breathing difficulties.

An allergy occurs when the immune system reacts to a substance or ‘trigger’ in the person’s environment that is typically harmless to them. Their immune system responds by making an antibody that attacks the allergen which triggers a range of immune system reactions.

Allergies can range from mild, moderate or severe with anaphylaxis being the most severe allergic reaction. It is said that one in 200 people suffer from Anaphylaxis.

A recent study showed that 69% of people would not know how to help someone having a severe allergic reaction and 70% did not know how to use the life-saving EpiPen device.
